About this trip

This eight-day route runs from Bangkok down through Koh Samui to Phuket, mixing included activities with long stretches of free time to fill as you please. Expect jungle, islands and beach in roughly equal measure.

A night in a raft house in Khao Sok National Park gives you jungle hikes and a shot at spotting wildlife, while a turtle conservation visit and plenty of beach time round out the pace. Getting between destinations involves real local transport, including a long overnight train.

It finishes in Phuket, though you only get a short stint there, so many people choose to stay on a few extra days.

What you'll do

  • Overnight train from Bangkok to Surat Thani
  • Stay in a traditional raft house in Khao Sok National Park
  • Jungle hike and wildlife spotting in Khao Sok
  • Learn about turtle conservation
  • Free time for snorkelling, swimming and waterfall trips on Koh Samui
  • End the trip in Phuket
Good to know
  • Basic trip style — most activities are optional, so you'll have a lot of free time to structure yourself
  • The 13-hour overnight train is basic, with shared compartments sometimes split across genders or with other groups
  • Only limited time in Phuket, so consider adding extra days there

Route map for 18 to 35s Essential Southern Thailand
  1. Bangkok — Bangkok

    Land in Bangkok, Thailand's sprawling capital, and settle in before a 6 pm welcome meeting. Arrive early to explore the city's markets, grab street food, or book a Thai massage. After introductions, head out for dinner with your group or hit the local nightlife spots your leader recommends.

  2. Explore Bangkok's highlights: Wat Pho, home to the famous 46-metre Reclining Buddha, and a nearby flower market. Spend the afternoon discovering other sites like the Grand Palace or Jim Thompson House at your own pace. Tonight, board an overnight train heading south to Surat Thani.

  3. Ko Samui — Koh Samui

    Arrive in Surat Thani, then catch a bus and ferry to Ko Samui. The island is yours to explore: beach-hop around the palm-fringed shores and coconut groves, or kick back and relax. Find dinner with new mates using your leader's recommendations.

  4. Join a half-day guided island tour with your leader to see Wat Phra Yai, the 15-metre Big Buddha. Relax at Na Muang waterfalls in the afternoon. Ko Samui's decades-old reputation as a tourist hub means decent nightlife—hit the bars and clubs after a curry dinner.

  5. Take a free day however you like: swim, sunbathe or explore. Optionally, tour Ang Thong Marine National Park's 40+ islands by slow or speedboat, swimming at Ko Mae and visiting Emerald Lake. Alternatively, visit Ko Tao or Ko Nang Yuan for quieter snorkelling, or spend time at Ko Samui's elephant sanctuary.

  6. Khao Sok National Park — Koh Samui

    Leave Ko Samui early, ferrying to Don Sak Pier, then drive to Chiew Larn Lake. Board a traditional longtail boat to your raft house in Khao Sok National Park—the wettest spot in Thailand with ancient jungle. Watch for wild elephants, gibbons and langur monkeys. Join an evening safari by boat deep into the jungle.

  7. Khao Sok National Park - Phuket — Khao Sok National Park

    Wake in the oldest evergreen rainforest on earth, your raft house nestled inside the park. Spot wildlife from a longtail boat through misty mornings, then hike the jungle—possibly finding waterfalls or panoramic viewpoints and glimpses of elephants, hornbills and langur monkeys. Head to Phuket, stopping at the Khao Lak Tsunami Memorial and Royal Thai Navy Sea Turtle Conservation Centre.

  8. Your trip ends this morning with no scheduled activities. Leave your accommodation whenever you're ready, or speak to your booking agent about staying longer in Thailand.

What's included

  • Guide: All group trips are accompanied by one of our group leader or local representative. The aim of the group leader or local representative is to take the hassle out of your travels and to help you have the best trip possible. Intrepid endeavours to provide the services of an experienced group leader or local representative however, due to the seasonality of travel, rare situations may arise where your group leader or local representative is new to a particular region or training other group leader or local representative. Your group leader or local representative will provide information on the places you are travelling through, offer suggestions for things to do and see, recommend great local eating venues and introduce you to our local friends. While not being guides in the traditional sense, you can expect them to have a broad general knowledge of the places visited on the trip, including historical, cultural, religious, and social aspects. At Intrepid we aim to support local guides who have specialised knowledge of the regions we visit. If you are interested in delving deeper into the local culture at a specific site or location then your group leader or local representative can recommend a local guide service in most of the main destinations of your trip.

What travellers actually say

Worth it if you're self-sufficient and can overlook poor leadership. Think twice if you need a guide who prioritises group safety and professionalism.

  • Tour leader slept through boat and van transfers, unable to monitor driver safety, lifejacket compliance, or medical emergencies.
  • Leader changed meeting points via chat without clarity, took personal calls during temple commentary, and started group dinners early without waiting.
  • Many passengers went without lifejackets on morning boat excursion; leader took no action despite safety guidelines requiring assessment.
  • Group split across two minivans with leader unable to monitor both vehicles during transfers between national park and Phuket.
